The Government's chief of surveillance will carry out the investigation into claims Tooting MP Sadiq Khan was bugged.
Sir Christopher Rose, who became Chief Surveillance Commissioner in July 2006, will lead the inquiry which is expected to take two weeks.
Jack Straw, Secretary of State for Justice, outlined the terms of the investigation in a statement to the Commons this afternoon.
Mr Straw explained Sir Rose would investigate claims Mr Khan was bugged while visiting his constituent, Babar Ahmed, at Woodhill Prison, Milton Keynes, in May 2005 and June 2006.
He explained the probe would attempt "to establish whether the visits were subject to any form of surveillance, and if so, with whose authority and whose knowledge".
The Sunday Times said Scotland Yard's anti-terrorist squad eavesdropped on conversations between the pair using a microphone hidden in a table.
BBC political editor Nick Robinson says ministers were not consulted and Mr Khan was not the target of the bugging.
It was claimed the operation was ordered by a Thames Valley police officer.
Mr Straw confirmed if the claims were true the surveillance breached a 40-year-old anti-bugging code known as the Wilson Doctrine.
